PART 1. AMMONIA CASALE PROFILE Ammonia Casale S.A. is one of the oldest companies active in the field of synthetic ammonia production, having been established in Lugano (Switzerland) in 1921 for the industrial development and commercialization of Dr Luigi Casale’s inventions for the catalytic synthesis of ammonia. Since the very beginning, and for many years now, Ammonia Casale has been active in the construction of new plants, with over 200 such plants built worldwide. The founder of Ammonia Casale: Dr. Luigi Casale In the more recent past, activities were mainly devoted to the revamping of existing plants, with more than 130 plants revamped in the last 15 years. The company is still involved in new plant construction through its licensees. At the present time, Ammonia Casale is a leader in the design of ammonia synthesis reactors and related process loops. The company is also a leader in ammonia plant revamping, having its own technologies to upgrade synthesis loop and syngas front-end units. Plant modernisations represent a very interesting aspect of Ammonia Casale’s support to clients aiming at increasing plant capacity or reducing energy consumption to within limits where the installation of much additional new equipment would entail TOTAL PLANTS 128 Revamping 111 Braun 4 Chemico 7 ICI 7 Kellogg 66 Topsoe 6 Various 21 79 IN SITU MODIFICATIONS New plants 17 IN OPERATION 120 Ammonia Casale Plant Upgrading and New Plant Designs between 1985 and 2001 4 CASALE ADVANCED TECHNOLOGIES FOR AMMONIA PLANTS - PART 1
substantial investment costs. This is achieved by boosting efficiency of key equipment (e.g. reactors), by partial or total replacement of the old internals with new ones, or by “in situ” modifications. Based on prevailing raw material and energy costs, the return on investment is usually high. The company can also claim the most experience in the comparison of uses of various different commercially available catalysts, and is in a position to guarantee optimal reactor performance with all these catalysts. The main strength of Ammonia Casale lies in the licensing of its technologies. Most of the technologies are developed in house by a team of very specialized and experienced people. Thanks to the innovative trend set by founder Dr Luigi Casale, plus the heritage and background of subsequent management teams, Ammonia Casale invested significantly in technology development. Casale Axial-Radial Reactor Design During the last decades this discipline evolved from an empirical art with an intuitive sense for good design into a more rationalised activity. Process design is now supported by sound insight into the chemistry of the processes, catalyst behaviours, kinetic data, heat and mass transfer phenomena, fluid mechanics, science of construction materials, and cost analysis. Ammonia Casale Technical Services avail themselves of specialists in all the above fields, as well as of sophisticated tools for investigating, analysing and picturing complex phenomena in a way unachievable with skilled manual calculations, including such tools as computer-aided techniques with applications ranging from chemical process design to fluid dynamics evaluations and mechanical stress analysis. In addition to the technology, Ammonia Casale can also provide all services required for the completion of a project, from engineering right down to construction, start-up and operation of the plant. The world has changed a lot since the industrial pioneers started out on their paths. New problems are at the forefront and press us for solutions; new needs urge to be fulfilled, often dramatically, such as the quest for a more efficient and environment conscious use of natural resources. Today’s Ammonia Casale has taken up the challenge and, still driven by the same spirit of commitment to excellence and achievement of its founders, offers to the world its most advanced state-of-the-art technology and expertise. 5 CASALE ADVANCED TECHNOLOGIES FOR AMMONIA PLANTS – PART 1
